Amino Acid Help!

I was diagnosed 6 months ago i have a few questions that im hopeing can be answerd,

First of i know alot you take l-glutamine which is one of 18 amino acids , now i been researching amino acid suppliments alot to help me with my bodybuilding to get an extra edge, in my research i have found alot of these amino acid suppliments are derived from rye and barley grains, will this affect me or it wont? Is it a case of examoles like bourban and whiskey wherebits been fermented and filterd enough to remove the gluten source? I am very keen but hesitant to add suppliments like bcaa's gaba and experemnt with other free forms like argine tyrosine valine phenylmethaline ect..so if you have some info you can share or experiencebi will most appreciative.
